Go Run Ultra sizing

Does it fit true to size? I normally wear a 13 or 13.5. Most shoe companies do not carry a 13.5. I have recently worn Pearl Izumi Trail N2 which is just a little snug. A 14 would definitely be too large. In HOKAS I have worn a 13.5.

The current version of the GRU runs 1/2 size large. As the others said, I went down 1/2 size and the fit is perfect. The upcoming GRU2 will be addressing the sizing issue, and should run more true to size. (I am currently wear testing the GRU2 for Skechers, which is how I know this)

Thanks for the feedback. I ordered a size 13 and will update how they fit when I receive them. I tried a pair of Altra Olympus size 13 and they were too snug. Toes were surprisingly cramped at the end of the shoe. Hopefully the Skechers work out.
